Scalable 3 kW, 48 V / 12 V Bidirectional DC/DC Converter

A complete 3 kW, 48 V / 12 V buck-boost converter has been designed utilizing an insulated metal substrate (IMS) with a heatsink for the power stage, with a standard FR4 controller board mounted on top and features six modular power stages capable of 500 W each.

48 V Resettable eFuse

An electronic fuse has been designed to switch loads up to 200A on a compact double-sided FR4 printed circuit board with passive cooling.

400 VDC, 100 A Bidirectional eFuse

Featuring SiC MOSFETs and a VOA300 optocoupler, this design handles continuous power up to 40 kW and operates continuously at full power with less than 30 W of losses and no active cooling, and also features a preload function, continuous current monitoring and overcurrent protection (with shutdown in less than 2.5 μs).

800 VDC, 50 A Bidirectional eFuse

Featuring SiC MOSFETs and a VOA300 optocoupler, this design handles continuous power up to 40 kW and operates continuously at full power with less than 25 W of losses without requiring active cooling.
